A long magnetic needle of length 2L, magnetic moment M and pole strength m units is broken into peices at the middle. The magnetic moment and pole strength of each piece will be
As we have learnt,
Pole Strength (m) -
It is represented by +m and -m.
-
Pole strength of each part = m
magnetic moment of each part = M' = m'L' = mL =

5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K
A capacitor is made of two square plates each of side 'a' making a very small angle
A solution of m-chloroaniline, m-chlorophenol and m-chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of NaHCO3 to give fraction A. The leftover organic phase was extracted with d
